Silicon waveguides embedded in lateral p-n junctions show field-induced optical nonlinearities. By properly polarizing the junction, these can be used to achieve electro-optic modulation through the Direct Current Kerr effect. In addition, these enable second-order nonlinear processes such as the electric-field-induced second harmonic generation (EFISHG).Single Mode Condition for Rib Waveguide: A New Criterion.

A perfect insulator does not exist because even insulators contain small numbers of mobile charges (charge carriers) which can carry current.In addition, all insulators become electrically conductive when a sufficiently large voltage is applied that the electric field tears electrons away from the atoms. The stress distribution in the Si rib waveguide is calculated by the finite element method, which is implemented in a COMSOL programme. Once the stress distribution is known, the local refractive index distribution can be evaluated using (5).
